What are some strategies for optimizing the performance of XML data processing in PHP applications, especially when dealing with large datasets?

When dealing with large datasets in XML processing in PHP applications, it is important to optimize performance to ensure efficient processing. One strategy is to use XMLReader instead of SimpleXML or DOMDocument, as it allows for streaming and does not load the entire XML document into memory. Additionally, using caching mechanisms like APC or Memcached can help reduce the overhead of parsing XML files repeatedly. 

// Example of using XMLReader for processing large XML datasets
$xmlFile = 'large_data.xml';

$reader = new XMLReader();
$reader->open($xmlFile);

while ($reader->read()) {
    // Process XML data here
}

$reader->close();
